With little warning the salty warmth of my Master's cum explodes in my mouth. The clinking of the chain leash against my thin metal collar stops as my attention shifts to swallowing every last drop of the thick liquid. It always catches me off guard how much of it there is, and I can feel my lungs burning for air as more of it is pumped into my mouth.
Finishing, my lips break the seal with a wet 'pop' and my eyes drift upwards to my Master, my heart speeding up as I anxiously wait for his approval. But he's not even looking at me, a book in his hand blocking my view of his face. My heart sinks at this realization and I slump a little on my knees, my eyes drifting to the floor.
A gentle tug of the leash brings my attention back upwards, and I shiver a little as I see him peering over the book at me.
"Open." He speaks clearly and firmly, his voice leaving little room for thought. I quickly straighten my posture and open my mouth wide for him. His eyes glare callously at me, examining my mouth to make sure not a drop of his cum remained. He leaves me suspended in anticipation for what feels like hours, his gaze roaming around my naked body as if searching for something out of place. It's moments like these where I most feel like his slave, so small and helpless before him.
The creaking of his armchair breaks the tense silence as he rises, I scramble backwards on my knees to give him space. He pulls his softening cock back into his pants and zips up the fly. In a single motion he gives the leash a firm tug, signaling me to follow, and turns towards the basement door.
"Bedtime slave." His tone is much more neutral, causing a sense of relief to wash over me knowing I succeeded in pleasing him with my mouth. Crawling after him quickly I'm able to avoid any painful tugs on my collar. He opens the heavy wooden door and flicks on the lights before stepping inside. Crawling down the stairs is still tricky, but he lets me take my time, waiting for me at each step.
Reaching the bottom of the stairs we're finally in the basement. It's a bare concrete room with a single light dangling from the ceiling. A simple metal wall locker is fixed adjacent to the door, and a small cage rests in the center of the room. I follow my Master to the door of the cage, and kneel patiently as he bends over to unlock it. The subtle ache of a nearly full bladder pulses through me, and I suddenly feel anxious again. As the cage door is opened in front of me I consider the long night alone, and I know I have to say something now.
"M-master?" I say timidly my body automatically tensing as he pauses.
He replies after a moment, "What is it slave?"
"I-I have to pee, M-master." My eyes drop to the floor as I feel shame wash over me. He sighs in evident annoyance and I brace myself for his anger.
"Wait until morning, it's time for bed." The ache pulses through me again and I raise my head to protest, but the cold tired glare he gives me sends my eyes right back to the floor.
"Yes, Master." I reply solemnly before slinking into the cage. It's not big enough to stand up or lay down, so I lay uncomfortably curled up on my side with the metal bars pressing into my back. Master closes the cage and locks it, then reaches a hand into the cage and unclips the chain leash from my collar. He turns without saying a word and begins climbing up the stairs. "Goodnight Master!" I call out after him as the heavy door creaks shut. The lock clicks and the lights go out, leaving me alone in the dark.
